I asked about it in another topic but case became really urgent.
1. Is carb rejet enaugh for 4-2 free flow exhaust and KN's replacement filter?
2.Or I can't have both?
3.Are bigger jets necessary?
I can have carbs rejeted day after tomorrow. I would rather prefer to be sure of that as soon as possible.
Sorry for asking about it again but it's really important.
